Normally samplers are installed at the ships manifold between the manifold flange and the flange from the bunker hose.

However, sometimes it is more practical to install the sampling device permanently at a different place.
The CMT Fuel Sampler is designed to be installed direct into an existing fuel pipe anywhere in the supply line.

It can easily be removed for cleaning. After initial installation the fuel line can be used with or without the sampler being inserted.
